Problem with left Blinker/High Beams

Maybe i'll get a bit more love in the 911 forum...

Recently, my left turn indicator stopped working and my high beams seem to want to engage whenever I drive over a bump. It seems like there may be something wrong with the switch in my steering column. Does anyone have any advice? Hopefully I have articulated my problem clearly... Thanks,

Replace the blinker (turn signal) switch. It sounds like it has issues!

Had a similar problem in my 84. Replaced the turn signal switch and that fixed it. I'm told the turn signal switches, at least in the 84-89, are notorious for going bad. Maybe there's a similar problem with your vintage.

yep... buy a new switch or get one from a breakers I've had two go over the years , you can fix them but not for long and they're a bit of a pain to fit too.

from looking at the diagrams for the early cars, all the headlight current goes through that switch. an additional relay would be permanent solution to the problem.

My '78 may not be like your car, but you might check into Marcus Sucro's relay kit. At $20.00 it is a bargain: all wired up with directions.

The turn signal/headlight stalk is famous for burning its contacts through too much current, esp. if you are running H4s or any other popular headlight upgrade in these cars. Cheaper than replacing that stalk I am sure!

I had the same problem in my 79SC, plus the wiper blades wouldn't park right. Took the steering wheel off and the half-clams around the two switches (turn and wiper) and pulled the old switches off to inspect. This is hard to describe, but once you have the switch off and can see how the mechanism works, it is pretty intuitive to fix. You'll see a number of metal contacts; one to engage the turn signal, and the high/low beam. Work the high/low back and forth and you'll soon see that one of the metal connections doesn't return to a position that keeps it from touching another metal contact (clear as mud, right?). I was able to slightly bend the high beam contact back to its original position and that fixed the problem. I know, I know - pix would have been helpful, but again, I think you'll find it pretty intiutive. The hardest part was getting the steering wheel back on in the original position. First try I was oriented in a left turn...d'oh!

Or, you can buy a new switch....

Joe
